Using chains and currencies in the API
Any time you refer to a currency in a Circle Mint API call, you use a currency
and chain pair. For example, to
create a USDC transfer
on Ethereum, specify the USD currency on the ETH chain.
When referring to balances, you only need to refer to the currency because the
value of the currency for Circle-hosted assets is independent of the chain.
